[Pkg-javascript-devel] Bug#650547: libv8: FTBFS on i386: unused variable in lithium-codegen-ia32.cc

[Aaron M. Ucko]

Source: libv8
Version: 3.5.10.24-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

The latest libv8 upload fails to build on i386:

  ../src/ia32/lithium-codegen-ia32.cc:3178:12: error: variable 'key' set but not used [-Werror=unused-but-set-variable]
  cc1plus: all warnings being treated as errors
  
  make[2]: *** [/build/buildd-libv8_3.5.10.24-1-i386-CPx3sU/libv8-3.5.10.24/out/ia32.release/obj.target/v8_base/src/ia32/lithium-codegen-ia32.o] Error 1

Could you please take a look, and reconsider your use of -Werror in
official uploads (which become fragile as a result)?

Thanks!
